nnslmnri'r SEAT MOUNT.

Application filed February 16, 1927. Serial No, 168,526.

V r This invention relates to an improvement in resilient seat-mounts which are particularly adapted for use in automobiles, but also useful in other situations where a shockabsorbing seat is desirable.

The object of this invention is to provide a simple and rugged resilient seat-mount constructed with particular reference to preventing undue rocking movement of the seat.

With this object in view, my invention consists in a resilient seat-mount characterized by a pair of'rocking-bars coupled together for synchronizing their movement and each having a pair of supportingarms.

The invention further consists in a resilient seat-mount characterized as above and having certain details of construction and combinations of parts as will be hereinafter described and particularly recited in the claims.

Inv the accompanying drawings:

Fig. 1 is a broken view in front elevation of a seat equipped with my improved resilient mount;

Fig. 2 is a plan view of the-mountingmechanism looking downward from the line 22 of Fig. 1; Y

Fig. 3 is a detached perspective view of one of the rocking-bars together with its arms; I

Fig. 4is a view corresponding-to Fig; 1 but showing another form which my inven tion may assume; and

Fig. 5 is a View corresponding to Fig. 3 but showing the form of rocking-bar e1nployed in the modified form of construction shown in Fig. 4.

In carrying out my invention, as shown in Figs. 1 to 3 inclusive, I employ two corresponding rocking-bars 10 and 11, each of which is provided at its opposite ends respectively with trunnions 12 having bearing in the upper end ofbrackets 13 upstanding from the floor 14 of an automobile or other suitable support.

Each of the said rocking-bars is also formed with two upwardly and outwardly inclined supporting arms 15 and 16, each of which is pivoted at its outer end to a link 17 which, in turn, is pivoted to the lower end of a bracket 18 depending from the under side of the seat 19.

In line with the arm 16 of each of the rockin -bars 10 and 11 and connected to it by an integral brace-member 20, is it depend ing coupling arm 21', to the lower end of which is loosely pivoted a ling 22. The inner ends of the links 22 just mentioned, one

of which extends inward from the coupling arm 21 of each of the rocking-bars, are perforated for the reception of fingers 23 projecting outward respectively from the opposite ends of an equalizing-lever 24, which latter is pivoted midway of its length to the support'14 aforesaid by means of a stud 25. i

From the foregoing it will be seen that each end of the seat is supported by the two supporting arms 15 and 16 "ofone of the rocking-bars 10 or 11, which are coupled together, as described, by the links 22 and lever 24, with the result that one end of the scat cannot move downward without causing a corresponding and substantially equal movement of the opposite end, these connections thus serving to maintain the seat in substantial parallelism with the floor 14.

' To yieldingly resist the downward movement of the seat 19, I preferably employ a large helical spring26 which is connected to one end of the lever 24 aforesaid and at its other end isconnected to the floor 14 by means of a stud 27, though I do not wish to limit my invention to any particular arrangement of spring or springs for yieldingly resisting the downward movement of the seat. V

In the modified form of my device shown in Figs. 4 and 5, I provide the rocking-bar 10 with a short upwardly and inwardly inclined coupling arm 28 and similarly provide .the rocking-bar 11 with a vshort inwardly surface of the floor 14.

.I claim: g 1. In a resilient seat-mount, the combination with a seat-member and a supportmember therefor, of a pair of rocking-bars, each formed with a pair of complementary supporting arms and with a crippling-arm its effectiveness by the seat 19 and the brackets 18 to the top extending substantially at a right angle with respect to the said supporting-arms, neans connecting the coupling-arms of the said rocking-bars together for synchronizing the rocking movement of the latter, means for securing the said rocking-bars to one of the said members with capacity for rocking movement, and means for connecting the outer ends of each of the said pairs. oflsupporting arms to the, other of the said members.
